This report presents details of a Warm Mix Asphalt (WMA) Evaluation Protocol. The Protocol guides the evaluation of specific WMA technologies and processes such as additives, surfactants and foamed bitumen, and sets out the conduct of appropriate laboratory tests and field validation projects so that the performance of WMA and conventional Hotmix Asphalt can be compared. The Protocol is an evaluation tool only; it is not a specification.
